I think a better analog to the Ways of Seeing (and eventually the Mystic Caste) are the Mentats from Dune. You get enough members of your Clan, who have been deeply trained in self-reflection and contemplation, coming up with enough similar visions, as a leader, you are going to see patterns and trends.
And this is borne out in what we see of Clan visions, and especially Mystics like Kisho Nova Cat--many of them have displayed what is essentially precognition through a regimen of stress, deprivation, and a forced surrendering of one's conscious modes of thought. Of course, this runs into the same problem that Thinkers (people with superpowers relating to perception) from the web novel
Worm do: given accurate information and an objective reading of the conclusions one's visions produce, they're some of the most dangerous people around...but if their initial assumptions are wrong, or if they take the wrong lesson from what they learn, they court disaster.
Additionally, once we get past the Ways of Seeing and into the Mystic caste, we now have to contend with the massive amounts of trauma and psychological harm done, starting from early childhood, as part of making have instinctual, correct, regular visions.
Heretic's Faith (or what I remember from it) provides glimpses of it: locked alone with other children (age 5 or so?) in pitch blackness, beaten for making noise, forced to fight for food and water, randomly tested, with failure meaning execution...eventually some of them stomp another child to death just so they'll be disciplined, to break up the monotony. I know the clans are written to be an utterly alien martial culture with Spartan methods, but the Mystic program should produce nothing but broken husks and serial killers. Let alone the suspect wisdom of whittling down a
sibko of some 50 trueborn warriors to a generous final count of 3 survivors, with any washouts culled...
